If the 2 were a +, then we would have %287g-2%29%287g-2%29 We cannot use our usual techniques here ,so we must apply the quadratic formula
x+=+%2828+%2B-+sqrt%28+784-4%2A49%2A%28-4%29+%29%29%2F%2898%29+
and then
x+=+%2828+%2B-+sqrt%28+1568%29%29%2F%2898%29+
and simplified as
x+=+%2828+%2B-+4sqrt%2898%29%29%2F%2898%29+
reduced we get
x+=+%2814+%2B-2sqrt%2898%29%29%2F49
